GUIDE-FLANGE FOR PAPER-ROLLING MACHINES.

SPECIFICATION forming part of Letters Patent No. 687,443, dated. November 26, 1901. Application filed February 1, 1901. Serial No. 45,555. (No model.)

To all whom it may concern.

Be it known that I, FRED SUCGIE, a citizen of the United States, residing at Brewer, in the count-y of Penobscot and State of Maine, have invented certain new and usefullrnprovements in Guide-Flanges forPaper-Rolling Machines; and I do herebydeclare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consistsof improved guideflanges for paper-rolling machinery, and is fully illustrated in the accompanying drawings, in which- Figure 1 is an isometric view of complete device mounted on a shaft. Fig. 2 is a side elevation of shaft, showing tapering screws and ends of lessened diameter. Fig. 3 is an enlarged side elevation of guide-flange. Fig. 4 is an enlarged side elevation of screw-clam p. Fig. 5 is an enlarged longitudinal section'of screw-clamp Fig. 6 is a side elevation of hollow core. Fig. 7 is an enlarged bottom view of guide-flange.

Similar letters refer to corresponding parts throughout the figures.

In the manufacture of pulp and paper the sheet as it comes from the machine is wound upon a hollow core mounted upon a revolving shaft, and in this process there is generallya tendency toward uneven winding, which produces a roll having one end concaved and the other convexed instead of fiat, a result which destroys the symmetrical form of the finished roll and makes packing and handling inconvenient and difficult. To remedy this dlfficulty, various devices are employed, and mine is described as follows:

The shaft A is formed with smooth spindles a a of lessened diameter at each end adj acent to its bearings B B to permit the fitting on of the guide-flanges O C, as hereinafter ex plained, and from points at or near its center is threaded with right and left hand screws a a, extending, respectively, to said spindles and tapering at their outer ends to the diameters of said spindles. A removable hollow core D, of a length about equal to the width of the sheets to be wound, having a bore of greater diameter than said shaft, is shipped upon the shaft near its mid-length and is rigidly clamped to the shaft and prevented from both rotary and longitudinal motion thereon by the screw-clamps E E, which consist of nuts working on the threaded portions of the shaft and having forwardly-projecting conical longitudinally flanged extensions e e, which extensions enter each end of the core and as the nuts are screwed toward the middle of the shaft by means of a wrench bear upon the inner surface of the core, the sharp I flanges of the extensions cutting into the core sufficiently to hold it rigidly to the clamp and through the clamp to the shaft.

Two guide-flanges C C are used, and each is constructed in the following manner: The flange proper, 0, consists of an annular thin stiff disk, preferably of metal, having a bore sufficiently large to pass over the end of the core and having a jaw 0 large enough to admit the screw-threaded portion of the shaft into the bore. The flange proper, c, is rigidly connected by a sufiicient number of arms with a split nut 0, formed to engage with the threading on the shaft and having a split or jaw c sufficiently large to admit the spindle a of the shaft into the bore of the nut, but not large enough to admit the threaded portion a of the shaft. The flange c and nut 0" may be formed integral, if desired. The rims of the clamps E E may be widened and screwthreaded, and the split nut 0" may be formed to work and turn upon said rims instead of upon the shaft, if such construction be preferred.

The disks 0 may be made of any desired diameter; but if in the process of winding one should be broken or a larger flange be re quired the nut 0 may be slightly turned back and a new or larger disk of the same pattern, but not connected with a nut, may be inserted between the original disk and the end of the roll and the nut again turned forward the shaft enters the bore of the nut and en-' gages with its interior threading, and the whole guide-flange being held by the hand at 00 or elsewhere and prevented from turning with the shaft is immediately screwed forward until the flange bears on the roll.

Any convenient method of clamping the core to the shaft may be adopted; but I prefer that above described-viz., the use of the screw-clamps E E.

Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, is-

1. In a paper-rolling machine and in combination with a winder-shaft having a screwthreaded portion intermediate its ends, and a spindle end of diminished diameter, and with a hollow core rigidly clamped to the central portion of said shaft, the herein-described guide-flange consisting of an annular disk and a split nut rigidly connected thereto and concentric therewith, said disk having a bore sufficiently large to receive said core and a jaw sufficiently large to admit the shaft-of the winder into said bore, and'said nut being internally threaded to engage with the windershaft and turn thereon and having a splitor jaw sufficiently large to admit the diminished end of the winder-shaft into its bore.

2. In a paper-rolling machine thecombination of a winder-shaft screw-threaded with a right-hand screw from at, or near, its center toward one of its ends and with a left-hand screw from at, or near, its center toward its other end, both ends of the shaft between its bearings and its screw-threadings being smooth spindles of diminished diameter; a hollow core having a bore of greater diameter than said shaft; a pair of screwclamps each being adapted to engage with the screw-threading on said shaft and having a forwardly-extending, longitudinally flanged conical projection adapted to enter the bore of said core; and a pair oftguideflanges each consisting of an annular disk having a bore sufficiently large to receive said core and a jaw sufficiently large to admit said shaft into its bore and being rigidly connected to, or formed integral with, a split nut threaded to engage with said shaft and turn forward thereon and having a split or jaw sufficiently large to admit the diminished end of said shaft into its bore.
